List

A basic list container backed by either array list or linked list.

List type

list<Type>

List creation

new arraylist
new linkedlist

Creates an empty list. Optionally, initial values may be specified right in the new list creation expression.

Alternatively, a sequence may be specified that is used to copy elements from.

Operations on list

iterator

This operation is redefined for list to return a modifying_iterator .

get

Yields the element at index position.

• indexed access
  list[index];

  set

  Operand type	Parameter type	Result type
  list<Type>	int Type	Type

  Sets the element at index position to the specified value. Yields the new value.
  list.set (index, value);
• indexed access
  list[index] = value;

  add

  Operand type	Parameter type	Result type
  list<Type>	Type	Type

  Adds an element to the list.
  list.add (value);

  addFirst

  Operand type	Parameter type	Result type
  list<Type>	Type	Type

  Adds an element to the list as the first element.
  list.addFirst (value);

  addLast

  Operand type	Parameter type	Result type
  list<Type>	Type	Type

  Adds an element to the list as the last element.
  list.addLast (value);

  insert

  Operand type	Parameter type	Result type
  list<Type>	int Type	Type

  Inserts an element into the list at the position index.
  list.insert (index, value);

  remove

  Operand type	Parameter type	Result type
  list<Type>	Type	Type

  Removes an element from the list.
  list.remove (value);

  removeFirst

  Operand type	Parameter type	Result type
  list<Type>	none	Type

  Removes the first element from the list.
  list.removeFirst;

  removeLast

  Operand type	Parameter type	Result type
  list<Type>	none	Type

  Removes the last element from the list.
  list.removeLast;

  removeAt

  Operand type	Parameter type	Result type
  list<Type>	int	Type

  Removes an element from the list located at the position index.
  list.removeAt (index);

  addAll

  Operand type	Parameter type	Result type
  list<Type>	sequence<Type>	list<Type>

  Adds all elements in the parameter sequence to the list.
  list.addAll (seq);

  removeAll

  Operand type	Parameter type	Result type
  list<Type>	sequence<Type>	list<Type>

  Removes all elements in the parameter sequence from the list.
  list.removeAll (seq);

  clear

  Operand type	Parameter type	Result type
  list<Type>	none	void

  Clears all elements from the list.
  list.clear;

reverse

Produces a list with all elements from the original list in the reversed order.
